Title: Channel access process for a local transmission system configured as a bus system
Inventor: SCHMICKLER LEONHARD
IPC: H04L12/40
Filed: 1990-09-10
Abstract: ABSTRACT      In a channel access process for a local transmission system configured  as  a bus  system  for  packetwise  transmission  of messages  without  central  control,  each  station  willing  to transmit monitors the transmission channel and transmits its message in function of the state of the transmission channel. Should a collision occur between messages in the transmission channel,  transmission of the messages  is interrupted and a collision resolution is carried out in a resolution phase.  The packets are transmitted in a sequence corresponding to the increasing  residual  length  or  residual  output  time.    The resolution phase which begins at the end of a collision consists of  possibly  several  time-segments  in  each  of  which  the transmission for the packets of messages of predetermined length or residual output time is released.

Abstract: A roll of plastic bags sequentially disposed in end-to-end relationship, each bag having two spaced handles, separated by a gap, and extending upwardly along the edges at the top end of each bag,  each bag being joined to a following bag by a perforated line, is disposed in a box-like dispenser having a front face.  A dispensing opening in the front face has a first cut-out portion and a second, spaced cut-out portion with a tab extending upwardly between the cut-out portions.   The tops of the cut-out portions, when joined together, define a bottom boundary overlying the cut-out portions and the tab.   The top of the tab and the bottom  boundary  are   separated  by  a  gap  which  is substantially wider than the thickness of the plastic bags.          Thus, when a bag is withdrawn, the handles of the next bag will fall into a respective one of the cut-out portions and lie outside of the dispenser so that the next bag is easily accessible for later dispensing.

Abstract: An electromagnetic attachment mechanism for use as an end effector of a remote manipulator system.  A pair of electromagnets 15A,15B, each with a U-shaped magnetic core with a pull-in coil 34 and two holding coils 35,36 are mounted by a spring suspension system 38,47 on a base plate 25 of the mechanism housing 30 with end pole pieces 21,22 adapted to move through openings in the base plate when the attractive force of the electromagnets is exerted on a strike plate 65 of a grapple fixture 20 affixed to a target object 14.  The pole pieces are spaced by an air gap from the strike plate when the mechanism first contacts the grapple fixture. An individual control circuit and power source is provided for the pull-in coil and one holding coil of each electro-magnet.  A back-up control circuit connected to the two power sources and a third power source is provided for the remaining holding coils. When energized, the pull-in coils overcome the suspension system and air gap and are automati-cally de-energized when the pole pieces move to grapple and impose a preload force across the grapple interface.  A bat-tery back-up 89A,89B is a redundant power source for each electromagnet in each individual control circuit and is auto-matically connected upon failure of the primary power source. A centerline mounted camera 31 and video monitor 70 are used in cooperation with a target pattern 19 on the reflective surface 67 of the strike plate to effect targeting and align-ment.

Abstract: STRUCTURE AND METHOD FOR TESTING ANTIFUSE RESISTANCE AND CIRCUIT SPEED                        David B. Parlour F. Erich Goetting ABSTRACT      In a configurable logic array chip having elements interconnectable by antifuses, an antifuse test structure is provided for estimating speed and resistance of programmed antifuses in the logic array without sacrificing any of the antifuses available for programming by the end user.  Antifuses programmable by the same means as those in the logic array are selectively programmed to form a test path having characteristics representative of a path formed by a user in the logic array.  A signal is propagated along this test path and time delay for propagation tested by switching the signal at a rate equal to a maximum acceptable time delay, then determining whether the signal propagates through the test path within the time before the signal switches.  In a preferred embodiment, the antifuse test structure is located along edges of the configurable logic array chip and each edge of the chip tested for acceptable delay.

Title: Load pressure duplicating circuit
Inventor: BIANCHETTA DONALD L
IPC: E02F9/22
Filed: 1990-08-30
Abstract: Load sensing hydraulic systems are useful for distributing fluid from a variable displacement pump to the individual work circuits in accordance with the demand of each work circuit. Preventing load pressure from being drained from the motors of the work circuits during some operating functions heretofore required the use of a pair of pressure compensating valves and a pair of shuttle valves at each of the directional control valves. The subject load pressure duplicating circuit (49) includes a single load pressure duplicating valve (52) having an end (62) subjected to the load pressure in a signal network (51) and reduces pump pressure entering the valve to a pressure level at the output thereof equal to the load pressure. This duplicated pressure is then utilized as the control fluid for the pressure compensating valves and a displacement controller (19) of the pump. The system is greatly simplified by the use of only a single duplicating valve for a hydraulic system having a plurality of work circuits.

Abstract: A biodegradable spun fleece is made of thermoplastic continuous filaments which adhere to each other at their crossing points without binder.  The filaments include at least 50 wt.% biodegradable polycaprolactone with a molecular weight of 35,000 to 70,000.  A process of manufacturing the spun fleece does not require an additional consolidation step after deposition of the spun filaments.  The use of a binder for the consolidation of the fleece is obviated.  The polymer material can be spun in conventional melt spinning arrangements.  The polycaprolactone material can be used in admixture with other materials which either cannot be melt spun in pure form or are not biodegradable and the resulting polymer mixture, surprisingly, can be melt spun and is biodegradable.
